WINDOW Application 1ed. April 18,

To all whom if may @0f/wcm:

Be it known that I, BENJAMIN F. AUrDinii-IEIDE, a citizen of the United States, residing at Davenport, in the county of Scott and State of owa, have invented a new and useful `Window Stoplock, of which the following is a specification.

My invention relates to improvements in window stop-locks, which are secured upon a window sash, and are commonly usedto coact upon the corresponding` upper or lower sash of a window having two or more sashes, but may be used in windows having only a single sash, and the objects of my invention are, first, to provide alineans yof locking a pair of window saslies at any given place with a single lock; second, to provide a window locking means more difficult for a burglar to release; andthird, to provide a window lock of more practical andv ornamental utility, at a more economic utility.

I attain these objectsby lthe mechanism illustrated in the accompanying drawings, in

which- Figure l is a side view ofthe stop-lock; Fig. 2, a front view of the stop-lock mounted with broken portions ofv a top and bottom sash of a window, disclosing the manner of attaching the stop-lock to the window frame y and its working between the two sashes, also disclosing pot hole platesattached to a member of one of said sash frames for such purpose; Fig. 3, a plan view in cross section .of the stop-lock complete, mounted on broken portions of an upper and a lower window f sash frame, taken on lin'e dL-a of Figure l; Fig. 4 a front end view of the stoploclr; Fig. 5, a side view in perspective of the inner sleeve; Fig. 6, a side view in perspective of the shaft; Fig. 7 a side view in perspective of the sleeve hub; Fig. 8, a side view in perspective of the cap washer; Fig. 9, a side view in perspective of the thinible cap; Fig. l0, a side view in perspective of the plunger; and Fig. il, a side view iii perspective of a broken portion of the tliimble.

Similar numerals refer to similar partsthroughout the several views.

Shaft 7, having a journaled end portion 7 and a tapering journaled spring seat portion 7b formsthe framework of the stoplock. Upon the journaled end 7EL of shaft 7, by means of a pin 15 inserted connectedly through transverse holes 8d of `sleeve said spring powerful action in releasing spring 10, and

STOPLOCK.

nut 8 and hole 7 f of shaft 7, I securely mount sleeve nut 8. Sleeve nut 8 corresponds in length to aboutone half the length of said j ournaled portion 7a of shaft 7, and in diameter is suitably larger than the body 71J of shaft 7, to workably accommodate the thickness of the spirals of spiral spring l0, which spiral spring 10 is mounted encircling the tapering journaled spring seat portion 7 b of said shaft 7, which tapering jouriialed spring seat portion 7b has a diameter at the end of Ouriialed portion 7a corresponding to the diameter of end portion 7 d, but which tapers foiI a distance corresponding tothe uncompressed length of vspring 10, until it reaches the flanged end -wall 7l1 of end 7d. Said spiral spring 10 is secured between sleeve nut 8 and sleeve 9, by being secured at one of its ends tosaid sleeve nut'S, by means of the right angularly bent end l()a of said spring, which is inserted in a longitudinal hole 8f provided therefor in the transverse end surface of said sleeve nut 8, the other end 10b of said spiral spring 10, being also bent right angularly and is inserted in a longitudinal hole 9d provided therefor in the transverse surface of the end of sleeve 9.

Sleeve 9 is loosely installed on the other end 7d of shaft 7, for the purpose of so connectedly attaching said spiral spring lO between sleeve nut S and sleeve 9, being to sccurely hold the ends l()a and 10b of spring lO so that it may be tightened by turning shaft 7 upon which sleeve nut 8 is mounted; and the purpose of providing the tapering journaled spring seat 7b portion of shaft 7, for '10, is to facilitate quick and to avoid any tendency in the spring lO to bind or rub against tliimble 3, by giving the spring 10 more room for action.

I mount thimble 3 upon shaft 7. over all, and hold itin place, with ils front end Il" 'lnstalled upon sleeve nut 8, ooactiiigly upon the jouriialed portion Se and the ribbon band 8b formed integral around, and spaced suitably betweeii the ends -of sleeve nut 8, and adapted to loosely lit in the boxed entrance to the center hole lb Of cap washer fl, and the boxed center hole 3d of the said thiinble 3, said sleeve nut 8 being mounted on the journaled end 7a of shaft 7 the rear end 3g of thimble 3 is installed on sleeve 9, which is installed on the rear 7d of shaft 7.

titl

Suiitably distanced from and upon the hori- Zontal surface of the end 7(1 of shaft 7, a guide pin 12 is installed in a transverse hole 7g provided in said shaft 7, which pin is of a length corresponding to the thickness of said inner sleeve 9, and is for the purpose of forcing sleeve 9 inward or outward Within thimble 3, by the sliding action of the pin 12 upon the angling Walls, of a spiral slot 9 provided in the Walls of sleeve 9, Which action is caused by the rotary movement of shaft 7 Within thimble 3, whereby the spiral spring 1() is compressed or relaXed as desired, and sleeve 9 is thus drawn Within thilnble 3 inwardly or forced outwardly upon shaft 7. Guide pin 12 is also used foi-the purpose of locking the sleevA 9 with spiral spring 10 in compressed position, when sleeve 9 fully drawn Within thimble 3, and ,spring 10 is fully compressed.

To facilitate the lockingof sleeve 9 in the Winding of spring 10, spiral slot 9c is provided with right angularly flanged shoulders 9f and 9g, suitable for engaging the sleeve 9 upon pin 12 When the end 9b of the spiral slot 9c is reached by the turning of shaft 7 Within sleeve 9 and thimble 3. The enlarged end 9b of slot 9c is longitudinally elongated, and the shoulders 9f and 9g are rounded for the purpose of facilitating a smooth movement of thepin 12 in and out of the said enlarged end 9b.

Sleeve 9 has holes 9e transversely disposed through itsWalls, positioned near one of its ends through Which a pin 13 is connectedly inserted through a transverse hole 11b provided inthe journaledend 11C of plunger point 11 when said journaled portion 11c is inserted in sleeve 9, thus leaving plunger tip 11"L fitting over the end of sleeve 9 flush, said tip 1l` being for the purpose of engaging in the hole 18a of plate 18, provided in one of the window sash frames in connection With which the stop-lock is to be used.

Iin 13 is secured in'holes 9c of sleeve 9, and hole 11h of plunger point 11, and is made suitably long to permit itsl protriiding ends to engage in the bifurcations 3", provided on either side of thimble 3. lifureations 3l provided on either side of thinible 3, provide vibrating` spare for pin 13. and are for the purpose of preventing sleeve 9 from rotating within thimble 3, when sleeve 9 is caused to slide in and out of thimble 3 by the movement of pin 12 in spiral slot 9U caused bythe turning of shaft 7.

Cap Washer 4 is mounted loosely with its reamed boxing 4 in contact With band Sl on short journaled end 8c of sleeve nut S, when said sleeve nut 8 is mounted upon the journaled end 7'n of shaft 7. Cap Washer 1 is eonnectedly secured to the flange 3a of thimble Bby screws `inserted in holes 3, thus creating a closed boxing, in which the ribbon band 8l) of sleeve nut S is made to revolve by journal cap 5 or handle (i, attached to shaft 7 and by spiral spring 1t).

Having mounted cap washer 4, and secured the same to the tiange 3 of thimble 3, I mount journal cap 5 upon the journaled end 7a of shaft 7, through horizontally disposed hole 5 securing the saine snugly against cap Washer 4 by pin means inserted connectedly through transverse hole 5l of the journal cap 5 and a transverse hole, 7c in the said journaled end 7" of shaft 7.

Journal cap 5 is suitably larger than the hole @te of cap washer ft, for the purpose of rendering the boxing 4t"-3 dust proof, and said cap 5 also serves as a thumb nut with Which to operate the stop loe-lt, but in my preferred form I attach a handle (i in longitudinal grooves 5C upon surface of journal cap 5 by which I turn the shaft, and thus draw the plunger 11 into thimble 3, or release it.
